//代码题 二、基于以下代码完成下面四个练习: 
const fp = require('lodash/fp')
const cars = [
    { name: 'Ferrari FF', horsepower: 660, dollar_value: 700000, in_stock: true },
    { name: 'Spyker C12 Zagato', horsepower: 650, dollar_value: 648000, in_stock: false },
    { name: 'Jaguar XKR-S', horsepower: 550, dollar_value: 132000, in_stock: false },
    { name: 'Audi R8', horsepower: 525, dollar_value: 114200, in_stock: false },
    { name: 'Aston Martin One-77', horsepower: 750, dollar_value: 1850000, in_stock: true },
    { name: 'Pagani Huayra', horsepower: 700, dollar_value: 1300000, in_stock: false }
]

//练习1：使用函数组合fp.flowRight()重新实现下面这个函数：
// const isLastInStock = function (cars) {
//     //获取最后一条数据
//     let last_car = fp.last(cars)
//     //获取最后一条数据的in_stock属性值
//     return fp.prop('in_stock', last_car)
// }
// console.log(isLastInStock(cars));  //false

//*****使用函数组合fp.flowRight()实现的代码：*****
const isLastInStock = fp.flowRight(fp.prop('in_stock'), fp.last)
console.log(isLastInStock(cars));  //false
